Schaufeli00aTowards a spiral model of the efficacy beliefs in the study of burnout and engagement a215-2310 v113 aIn this study the Downward and Upward Spiral Model of efficacy beliefs is tested in two samples of Spanish (N=203) and Belgian (N=150) university students respectively. Results from Structural Equations Modeling showed empirical support for the Downward Spiral Model of burnout, which is considered as a crisis of efficacy , and for the Upward Spiral Model of engagement, which as a boost of efficacy . Results also show empirical support to the mediating role that efficacy beliefs play in the relationship between past success and burnout/engagement on the one hand, and self-efficacy beliefs about academic success on the other hand. Moreover, using multigroup analysis it was shown that the research model was invariant of across both samples. a1134-7937 a2174-0437
